Originally developed in response to restrictive knife laws in England that prohibited the carry of one-hand-opening lock-blade knives, the UK Penknife™ was the trailblazer of Spyderco’s unique SLIPIT™ line of knives. These knives combine the defining features of our revolutionary CLIPIT® platform—a pocket clip and our Trademark Round Hole™ for one-handed opening—with the legal and social friendliness of a non-locking mechanism. This expression of the UK Penknife makes history again as the first non-locking member of our ultra-corrosion-resistant Salt® Series. Its full-flat-ground, leaf-shaped blade is precision machined from CPM® MagnaCut® steel—a revolutionary particle metallurgy steel that offers an impressive balance of edge retention, toughness, and extreme corrosion resistance. The blade is available in both PlainEdge™ and SpyderEdge™ formats and is housed in a high-visibility yellow handle constructed with injection-molded fiberglass-reinforced-nylon (FRN) scales and a marine-grade backspacer and hardware. A reversible deep-pocket wire clip completes the package, ensuring this fearlessly corrosion-resistant cutting tool is both left and right-hand friendly.
